Abstract: The apparatus to apply patterns and/or characters to glass or ceramic products  uses electrophotography, and has an intermediate carrier in direct contact with the surface of the product being decorated. At least two coronas are used, where the first is at the intermediate carrier and the second is at the contact zone between the intermediate carrier and the product. The apparatus to apply patterns and/or characters to glass or ceramic products (2) uses electrophotography, and has an intermediate carrier in direct contact with the surface of the product being decorated. At least two coronas (9,10) are used, where the first (9) is at the intermediate carrier and the second (10) is at the contact zone between the intermediate carrier and the product (2). The intermediate carrier is formed by a transfer roller (7) with shape stability. The second corona (10) is under the product (2), directly in the contact zone. A hollow counter roller (11) is under the product (2) in direct contact with it, with the second corona (10a) within it or at the surface in the contact zone. The first corona (9a1,9a2) is at the transfer roller (7) in the contact zone with the image roller (5), with an opposing potential to the charge of the toner image on the image roller (5). A further and third corona (9b1,10b) is at the transfer roller (7), in the contact zone with the product (2), with an opposite potential to the first (9a1,9a2) and second (10a) coronas at the counter roller (11). The transfer roller (7) is hollow, with at least one internal corona (9a1,9b1). The hollow transfer roller (7) has an electrically insulated plastics core (7a), preferably with a reinforcement of glass or carbon fibers, and a thin and relatively soft conductive layer (7b). Within the roller (7) there is an upper corona (9a1) at the contact zone with the image roller (5) and a lower corona (9b1) with an opposite potential. The transfer roller core (7a) can be of metal with an insulating layer 2 mm thick, covered by a conductive layer, with an upper and external corona (9a2) at the contact zone with the product (2) and a lower corona (10b) with an opposite potential.

Abstract: The invention relates to a method for producing two differently doped adjacent regions in an integrated semiconductor. During the production of integrated semiconductor structures, it is often necessary to differently dope immediately adjacent regions. The aim of the invention is to provide a method for carrying out the targeted higher doping of such regions in an easier and more economical manner. To this end, the invention provides a method for producing two adjacent regions of a predetermined area in an integrated semiconductor, whereby a first region of the two adjacent regions comprises a doping with a lower target concentration than a second region. The method comprises the following steps: Doping the predetermined area (5) of a semiconductor blank with a dopant until a concentration of dopant (12b, 12c) is obtained which is at least as high as the target concentration of the second region; applying a protective layer to the second region, and; out-diffusing the dopant from the first region until a concentration (12a) of dopant is obtained which corresponds to the target concentration of the first region.

Abstract: In die Zufuhrleitung (10) eines Sprinklerrohrnetzes wird von einer Druckgasversorgung (41) ein inertes Gas eingespeist, damit keine gefrierende Flüssigkeit in den Rohren enthalten ist. Die Schnellöffnungsklappe (45) eines Löschventils (40) trennt die mit Flüssigkeit gefüllte Löschwasserleitung (20) von der mit Gas gefüllten Zufuhrleitung (10). Im Falle des Ansprechens eines oder mehrerer Sprinkler wird die Schnellöffnungsklappe (45) nur dann geöffnet, wenn zugleich ein Brandmelder (13) an eine Brandmeldezentrale (14) Feuer gemeldet hat. In diesem Fall wird ein Auslöseventil (42) geöffnet, welches Druckluft von einer Zufuhrleitung (48) über eine Drossel (51) und eine Verbindungsleitung (55) in die das Gas enthaltende Zufuhrleitung (10) einspeist. Dadurch sinkt der Druck einer Leitung (60), welche über einen Zylinder (74) eine Arretierstange (73) im Haltezustand hält. Bei abgesunkenem Druck in der Leitung (60) wird die Arretierstange (73) zurückgefahren und die Schnellöffnungsklappe (45) wird geöffnet. Bei Leckagen im Sprinklerrohrnetz wird der Gasverlust über die Verbindungsleitung (55) ausgeglichen, ohne daß die Schnellöffnungsklappe (45) geöffnet wird.

Each blade (13) of the impeller wheel (10) is pressed with the upper face (8) thereof onto the peripheral wall (3) of the drive wheel (2) by a spring element (17). According to the invention, each blade (3) of the impeller wheel (10) can be additionally pressed, with its upper face (18), in a radial manner against the peripheral wall (3) of the drive wheel (2) by the pressure force of the hydraulic pressure medium that can be introduced in a targeted manner onto the lower face (16) thereof. This pressing is effected by virtue of the fact that each blade has, on one or both of its faces, at least one additional pressure medium channel (21) that leads out from its lower face (16).

A control circuit controls the semiconducting switch of the first LED string (called the master string) so that a constant average of the LED current is attained. The master string has a given number of LEDs in a string. This control circuit also controls at least the semiconducting switch of a further second LED string (called the slave string).
